OSCAR M. STIMSON, OF CHICAGO, ILLINOIS.

COMBINED FREEZER AND REFRIGERATOR cAR.

Be it known that I, OSCAR M. STIMSON, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented new and useful I-m rovements in a Combined Freezer and Re i er ator Car, of which the following is a spec' cation.

This invention relates to a combined freezer and refrigerator car; and the object thereof is to set up a car in .a manner as'hereinafter, set forth which is particularly adapted for freezin' or for refri erating purposes age or house refrigerators.

By way of explanatlon it might be well to state that there are to-day in service'two or more special cars which are required to meet the varying conditions when transporting perishable products and which may be,

I termed a refri crater-oar and a freezercar. The refrigerator-car is rovided with ice-boxes adapted to receive t e ice and by which a temperature from 359 to 50 can be .f maintained, and the freezer-car, which is used largely for hauling fresh meat, poultry,

, and other fresh and frozen packing-house roducts, requiring a temperature of 35. and ess. The freezer-car requires anespecial e uiplment, which cannot be ventilated and W lILlC is not entirely successful asthe refrigerator-car referred to, for the reason that In the freezer-car the ice receptacles or chambers are entirely inclosed, which they must of course be in order to carry the brine accumulated from melting ice and salt.

this invention is. to

- Figure 1 is a longitudinal sectional view of ing the ice-boxes, to be hereinafter referred re uires the carcan be ventilated. At. each 9.5 rectangular spaces is arranged anlce-box, a

while the remainder of the upright members the conductor-pan, and those members of the are of a length slightly less than half the height of the interior of the car. .The side and front walls are formed of a plurality of upright members suitably spaced apart, and the said members are of a length slightly less than half the height of the interior of the car. The slatted front wall 12 has secured to the outer face thereof a wire screen 16 or a perforated metallic sheet, which rovides an additional cooling-surface and, lilrthermore, prevents small pieces of ice falling into the loading-chamber. At the lower ends of the upright members of the front, side, and rear walls longitudinally-extending grate-bars 17 are provided and which constitute the bottom of the ice-box. These bars 17 may be of any suitable construction and are arranged in separate series in such a manner that one series will be spaced apart from another series for a purpose to be hereinafter referred to, and the said bars of each series are suitably spaced apart. v

The bars 17 are supported by the conductor-pan, to be hereinafter referred to, and the said conductor-pan is mounted upon the supports 18, these latter being in the form of T'- irons and are secured to the uprights 11 and the vertically-extending members 11 1 1 1 1 1 1 of the rear wall 13. The uprights 11 and vertically-extending members 11*, 1 1 1 1,

and 11 are mortised to receive the supports tirely around the same.

18, as clearly shown in Fig. 5[ The bars 17 not only constitute the bottom of the ice-box, but also act as a means to protect the conductor-pan, as will be evident.

The conductor-pan is indicated by the reference character 19, is substantial] rectangular in contour, and of a width an breadth equal to the width and breadth of the icebox. The said conductor-pan 19 is formed ofa series of sections 19 19 19 '19 19. The sections 19 19, and 19 are provided with vertical flanges 19, which extend in a longitudinal-direction, and thesections 19 and 19 are not only provided with-the longitudinallyextending flanges 19 similar to the flanges 19, but are further provided with the horizontally extending flanges 19 By such construction when the sections are set up to constitute the drip-pan the same is provlded with a vertical marginal flange extending en- The sections 19 and '19 are cut away, so as to provide the conductor-pan with a pairof openings 20, and the said sectio], 19 and 19 are each rovided with a de'ending flange 21. Theiilnction of the con uctor-pan 19 is to collect the drippings from the ice-box and direct them into the tank; The conductor-pan, as

- shown, is provided with two openings 20; bi'it it 'is evident that only one opening may be employed. The n right members of the front and side wal s are cut away at their lower ends, so as to overhang the vflanges of the member 28, which is secure rear wall which are of a length less than half the height of the car are also cut away, so as to overhang the flange of the conductor-pan.

The ice-tanks are indicated by the reference character 22. One or more of these icetanks may be employed, as shown'two, for the reason that the conductor-pan is provided with a pair of openings. If the conductor-pan be rovided with but one 0 ening, one ice-tan is em loyed. Each 0 the ice-tanks 22 consists 0? a receptacle having closed sides, a closed bottom, and an open top, and the said tanks 22 are arranged below the openings 20 of the conductor-pan 19 and below the space formed between two series of grate-bars. The tanks 22 are not connected to the conductor-pan, but are arranged a suitable distance belowsaid an, thereby permitting of the tanks over owing. The

tanks 22 are somewhat narrower than the conductor-panand are provided withwooden bottoms 23 to rotect the tank from falling ice, and on the ont oron one side of each of the tanks near the bottom thereof a handhold 24 is formed to permit of cleaning the tanks when so required. Supports "25 are provided for the tanks 22, and these supports '25are adapted to have the tanks 22 seat thereon and are of such height as to elevate the tanks a suitable distance above the floor of the car. Owing to the arrangement of the tanks 22 with respect to the ice-box, it will be f seen that the drippings from the melting ice in the ice-box are conveyed into the said tanks, thus carrying the drippings, which are of course very cold, until the benefit of the temperature has been obtained. When the tanks shall have become full of the dri' pings,

they will overflow and escape down t e out side of the tank into the drip-pan26.

The drip-pan 26 is constructed of suitable metallic'material of a width equal to the width of the car positioned below the'icetanks 22 and has its forward end projecting upwardly at aninclination, as at 26, and the said inclined portion 26" is supported u on to the of the car. The inclined portion 26 of the drip-pan constitutes a means to arrest the drippings and overflow fromthe tanks flowing out upon the floor of the car. pan 26 has communicatin therewith apair .of drain-pipes .27. These atter open into atrap 29, carried by the bottom of the car. The outlet .29 of the trap 29 communicates oor The drip-.

with a pi e30, which is of such length as to convey t 6- salt or the brine drippings to a point below the metal work of the car-truck, so as to prevent thereto.

Positioned forwardly of the uprights 11 is a solid door 31. of such he' ht as to partially inclose the front wall of t e ice-box and to partially inclose a portion of the'space in which is arranged the tanks22, and owing to the height and arrangement of the 'door 31 1 as shown, the retarding of the circulation is to the uprights 11..

Each of the hatch-openings is closed I through the medium of a plug 31, which when the car is ventilated is adapted to drop down into the ice-box. The plugs are connected to the top of the car by the chains 33.

The tanks 22 are not used solely as dripcollectors, for the reason that they form an essential part of the ice-storage, as the top o enings of these tanks are not covered by t 1e grate-bars, but the tanks open directly into the upper section of the ice-chamber. Therefore when the ice-box is being filled with ice it is evident that the ice will also fall ,into the ice-tank. The dimensions of the cooling-surface for the descendin the front thereof thereby establis tanks 22 are such that the tanks can be employed for the use of either caked or crushed ice, and the arrangement of the tanks is such that it is necessaryto first fill them with either caked or crushed ice before it is possi ble to fill the ice-box.

For medium temperature no salt or similar substance is used, yet the melting of the ice will naturally in time fill the tanks, which is a desirable feature even when medium temperature is required, but an actual necessity when afreezing temperature is required and obtained by the use of salt or other similar iubstance and by collecting and holding the rine.

The tanks are in time filled with water or brine as the ice melts, and in time theremaining ice in the tanks will vnecessarily float on the top oflthe water. Consequently it will thereby be brought to a higher point inthe car or near where the air 'enters the refrigerating-chamber. In; addition these tanks by overflowing provide an extra large air-current. ,When the car is,to be vent' ated, the ventilating devices are opened, the plugs of the hatch-openings removed, and the air can then enter through the hatch-openings at oneend of the car and pass out of the hatchopenings at the other end of the car.
